The official version of Fedora15, codenamed Lovelock, is officially released today. For details, see the Chinese release announcement. Fedora15 is equipped with a brand new Gnome3 desktop environment and provides a large number of new features and new components. The main features of Fedora15 include: Gnome3 desktop environment: This is the main version of the Next Generation Gnome environment, providing a brand new desktop interface GnomeShell. Libreoffice office suite: The official version of

inconsistent with the registration record above, and the MX record configured for its cname record value is the result of recursive query on the cname record. However, if the ttl of the recursive server's cname record expires, the query will be performed again, but the query order will be reversed (that is, the MX record will be queried first and then the cname record will be queried) the expected results may be obtained. To sum up, when the recursive DNS server queries a regular Domain Name Re

machines (or even the entire LAN), and (2) to the end-to-end packet traffic security, which is done by the computer as the endpoint. Any of these patterns can be used to build a virtual private network (VPN), which is one of the most important uses of IPSec . It should be noted that the above two modes of operation are very different in the implementation of security. The development of Internet-wide end-to-end communication security is slower than expected, partly because it is not widespread

Because the DNS system itself is unreliable (especially in the era of SSL design, even DNSSEC has not been invented). Due to the unreliable DNS (the existence of "domain spoofing" and "Domain Hijacking"), you see the URL inside the domain name "not necessarily" is the real drop!(Do

The Red Hat project team will continue to participate in the development of Fedora and will invite and encourage more external participants than ever before. By adopting such a more open process, we hope to provide an operating system that is more in line with the concept of free software and more attractive to the open source community.

When I got to a new company, I had less time to study and was busy every day. In some ways, there was indeed resistance. However, I have been learning for a long time, but it lacks coherence.
